nRF52 sniffer for mesh

[au]

Hi,

I've installed nRF sniffer version 2-0-0-beta on nRF52832 DK and verified it with BLE Beacon example. It works nice.

But when running light-switch example from Mesh SDK I don't see any packets in wireshark. Moreover, the wireshark doesn't see the device with such MAC address at all.

Any ideas?

Please use Wireshark version 2.6.2 or later for sniffing BTLE Mesh messages.

Dissector to use use -> btmesh

Set the Network keys and IVIndex in -> Preferences -> protocol -> Bluetooth -> BT Mesh

***Unfortunately this will only decrypt using the network key, decryption of the application key is not yet available.

I was given the net_key by another part of my embedded team, but not an IVIndex.  Is there a default?

Where do you have the "btmesh" dissector from? I cannot find it in the Plugins list of wireshark v2.6.7

In my sniffer, the "BT Mesh" protocol is enabled. But data is not decrypted, see example below...
